2 Claims.

My invention relates to dispensing, and more particularly to means forintermittently dispensing fluid, for instance, disinfectant, deodorizersand/or solvents into flush tanks or the like.

Oneof the objects of my invention is to provide a dispensing devicewhich .isso constructed and arranged whereby the same may be placed andsupported withinthe flush tank of a toilet for supplying the tank with adisinfectant or the like at predetermined intervals.

Another object of my invention is to provide a dispensing device of theforegoing-described character which is equipped with a fluid actuatedvalve mechanism adapted to be operated by the filling and dischargingaction of the water of the tank.

A further object of my inventionis'to provide a dispensing device" ofthe foregoing described character which is so constructed and arrangedwhereby a bottle cf'disinfectant fluid may be inserted within the tankwith the contents being dispensed by the fluid actuated valve mechanism.

An important object of my invention is to provide a device of theforegoing described character which is simple in construction, durablein use, efficient in operation and economical in manufacture.

With the above and other objects in view, as will hereinafter appear,the invention consists in the. combination and arrangement of partshereinafter set forth and illustrated in the ac companying drawings.from which the. several features of the invention and the advantagesattained thereby will be readily understood by those skilled in the art.

Referring to the drawings wherein like reference characters designatelike parts throughout the several views:

Figure l is a side elevation of my invention as applied to a flush tank.

Figure 2 is a sectional view taken on the line 22 of Figure 1illustrating the valve-mechanism within the flush tank 6 of a toilet.The bracket 5 removably supports a container, for instance, a bottle 1within the tank and which bottle contains a fluid disinfectant. Thebottle I. is of a type having an exteriorly threaded neck 8 disposeddownwardly within the flush tank and in predetermined relation with thelevel 9 of fluid or water within the tank when the latter is filled.

The contents or disinfectant of'the bottle. I is discharged inpredetermined quantities into the tank bymeans of a fluid or wateractuated valve mechanism, the latter being responsive to the rise andfall of the water in the tank during flushing and filling of the latter.The valve mechanism comprises a cap Ill threadily connected about theneck 8 of the bottle I and is provided with a centrally disposed sleeveH extending axially through its end radial wall and in which is slidablymounted a cylindrical valve stem [2 having a. diameter of a size to forma discharge passage l3 about the inside face of the sleeve II. The loweror outer end of the valve stem I2 has secured thereto the radial endwall of an inverted cylindrical cup or float member [4, while the upperor inner end of the stem I 2 has applied thereabout a rubber gasket orstop member 15 for limiting the downward movement'of the stem l2 andeffecting a seal with the upper or inner end of the sleeve ll. The outeror lower end of the stem l2 has secured thereon, between the lower orouter end of the sleeve II and the cup 14, a gasket or sealing member 16for limiting the upward move.- ment ofthe stem and sealing of the lowerend of the sleeve about the stem. Subjacent its upperend, the stem I2 isformed with a diametrically reduced section [1 which cooperates with thesleeve toform a disinfectant receiving chamber l8.

In operation-assuming disinfectant is contained within the bottle I, thevalve stem I2 in raised position by reason of the level 9 of the waterwithin the tank 6, and the chamber [8 filled with disinfectant asillustrated in Figure 2it will be apparent that when the tank is flushedandthe Water level 9 therein thus'lowcred, that the valve stemv [2 willmove downwardly a distance to effect engagement and sealing' relation ofthe gasket l5 with the top of the sleeve II and at thesame time open thelower end of the passage l3-to permit discharge of the disinfectant,containedzin the chamber l8; into the tank as illustrated in Figure 3.As the water rises in the tank, the valve stem l2 will be actuatedupwardly within the sleeve II and effect sealing engagement of thegasket I6 with the lower end of the sleeve to preclude leakage ofdisinfectant from the chamber I8 and permit filling of the latter bydisinfectant within the bottle. Obviously, by axially adjusting thegasket 16 relative to the stem l2, the amount of disinfectant dischargedmay be varied, it being understood that the rate of discharge ofwaterfrom the tank and the water level remain the same.

When it is desirable to thoroughly clean the valve mechanism, the gasketl may be removed from the valve stem [2 and the stem disassembled withrespect to the cap and sleeve. Furthermore, the gasket may be adjustedrelative to the stem 12 in lieu of the adjustment of the gasket l6.

If desired, a modified form of container or bottle may be employedwhich, as illustrated in Figure 6, has its inverted bottom endformed'with P a relatively thick wall'through which is formed an opening26 for receiving a hook or the like carried by the tank whereby thebottle 25 may be suspended therein without the use of the bracket 5 orthe like.

Without further elaboration, the foregoing will so fully explain theinvention that others may,

'by applying current knowledge, readily adapt the same for use undervarious conditions of service. Moreover, it is not indispensable thatall the features of the invention be used conjointly since they may beemployed advantageously in various combinations and subcombinations.

It is obvious that the invention is not confined to the herein describeduse therefore asv it may be utilized for any purpose to which it isadaptavarious forms, and the invention comprehends all constructionwithin the scope of the appended claims.

What I claim is:

1. In a device of the character described, a

closure cap adapted to be detachably secured to the opening of aninverted fluid container secured within a flush tank, a sleeve fixed toand extending through said cap and having upper and lower ends withrespect to said container, a

valve stem slidably mounted within said sleeve and having upper andlower end portions relative to said ends, said sleeve having a bore of agreater diameter than the diameter of said stem to thus provide a fluidpassage about said stem, said stem being formed between said portionswith a diametrically reduced section defined by a pair of radial andconfronting upper and lower end faces, said faces coacting with saidsleeve to provide a chamber between said portions for receiving fluidfrom within said container for discharge into said tank through saidfluid passage, a float depending from said lower end portion for movingsaid stem upwardly and downwardly within said sleeve upon the rise andfall of fluid within said tank, respectively, upper and lower gasketsfrictionally secured-on said upper and lower end portions for limitingthe down-' ward and upward movements, respectively, of said stem and forsealing said ends of said sleeve when engaged therewith, said upper endportion being limited to a predetermined length only sufficient toconfine said upper gasket to a position thereon for rendering said uppergasket effective at all times for maintaining said lower face withinsaid sleeve when said upper gasket engages said upper end upon downwardmovement of said stem whereby, discharge of fluid from said chamber intosaid tank by way of said passage and said lower face is precluded .fromengagement with. the lower end of said sleeve during upward movement ofsaid stem.

2. In a device of the character described, a closure cap adapted to bedetachably secured to the opening of an inverted fluid container securedwithin a flush tank, a sleeve fixed to and extending through said capand having upper and lower ends with respect to said container, a valvestem slidably mounted within said sleeve and having upper and lower endportions relative to said ends, saidsleeve having a bore of a greaterdiameter than the diameter of said stem to thus provide a fluid passageabout said stem, said stem being formed between said portions with adiametrically reduced section defined by a pair of radial andconfronting upper and lower end faces, said faces coacting with saidsleeve to provide a chamber between said portions for receiving fluidfrom within said container for discharge into said tank through saidfluid passage, a float depending from said lower end portion for movingsaid stem upwardly and downwardly within said sleeve upon the rise andfall of fluid within said tank, respectively, upper and lower gasketsfrictionally secured on saidupper and lower end portions for limitingthe downward and upward movements, respectively, of said stem and forsealing said ends of said sleeve when engaged therewith, said upper endportion being limited to a predetermined length only sufiicient toconfine said upper gasket to a position thereon for rendering said uppergasket effective at all times for confining said lower face within saidsleeve when said upper gasket engages said upper end upon downwardmovement of said stem whereby, discharge of fluid from said chamber intosaid tank by way of said passage and said lower face is precluded fromengagement with the lower end of said sleeve during upwardmovement ofsaid stem, one of said gaskets being axially adjustable on said stem tovary the operating stroke of said stem for controlling the discharge offluid from said container into said chamber through said passage, one ofsaid gaskets being removable from said stem to permit disassembly ofsaid stem relative to said 1 sleeve for cleaning of said chamber.
